Chemistry of Uranium in brines related to the spent fuel disposal in a salt repository

Abstract

This report describes the work performed from september 1991 to december 1992. Our work is focused on the chemistry of uranium in highly saline solution. Experiments were performed to study the formation process and the stability of solid phases of U(VI) in NaCl solution at different ionic strength. The characterization of solid phases and of uranium concentration in solution are reported as a function of time. Experiments in NaClO{sub 4} at low concentration have been performed for comparison. A method is proposed for uranium analyses in highly concentrated salt solution. The work has been carried out in KfK (INE), Germany. (Author) 10 figs.
